Helping Engineers Sort Out PEI in Pump Selection and Efficient System Design
With HVAC systems accounting for as much as 50 percent of a commercial building’s energy use, efficiency is a priority in system design. A new Department of Energy pump efficiency standard is changing the way engineers select pumps for hydronic systems.
Beginning Jan. 27, 2020, clean water pumps sold in the United States must achieve a minimum energy rating of 1.0 as outlined in the Energy Conservation Standards for Pumps established by the U.S. Department of Energy (DOE) and adopted by Natural Resources Canada. Even though that number denotes compliance with the new standards, a compliant pump by itself is not a measure of an efficient hydronic HVAC system.
